Introduction of Buddhism to Sri Lanka
Theravāda Buddhism was introduced to Sri Lanka in 247 BC by Arahant
Mahinda Thera during the reign of King Devānampiyatissa (250–210 BC). From
that day onwards, for over 2268 years (up to 2021 AD), Buddhism has
continued to be the principal motivating force behind most activities of the Sri
Lankan people.
At the same time, the teachings of the Buddha gradually became practised as a religion among the common people.
